--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> ---
What if the function is not called indirectly, wouldn't the implicit object ref
just be garbage?
My response to this is "just use C++". Then you have functions which are
guaranteed by the language to be "member" functions, so always have an object
ref, and it's guaranteed to be available with portable spelling ('this').
Otherwise this is yet another C++ feature being added to C because people want
features from C++ (inline, constexpr, lambdas, namespaces, member functions
...) but won't use C++.
